About CW7YYZZ
CW7YYZZ is the ICD-10-PCS code for a systemic nuclear medicine therapy procedure on the anatomical regions, multiple using an other radionuclide approach with none (qualifier: none). In ICD-10-PCS, systemic nuclear medicine therapy means introduction of unsealed radioactive materials into the body for treatment.
In plain terms, this corresponds to injection or instillation of radioisotopes, the ICD-9-CM procedure title it maps to (92.28).
For a different body part, codes include CW70YZZ (abdomen), CW73YZZ (chest), CW7GYZZ (thyroid) and CW7NYZZ (whole body).
It doesn't appear in the MS-DRG procedure index, so on its own it doesn't change the DRG assignment.
It has been valid since ICD-10-PCS took effect on October 1, 2015.
